In order to observe photocatalysts reactions, rGO/ZnO/Cu nano-structure was synthesized through total reflux combined hydrothermal method. The effects of adding rGO and Cu doping on ZnO lattice were assessed. FE-SEM, TEM, EDX analysis, and XRD tests were used to study the morphology and particle size of the catalyst. The XRD-SAXS verified the crystallinity of the catalysts. FTIR and Raman spectroscopy characterized the mineral oxide-GO bonds also DRS was applied to study the band gap. Photocatalytic degradation efficiency was investigated by methylene blue solution and 25 mg photocatalyst is the best dosage for degradation.

合成的rGO / ZnO / Cu光催化降解亚甲基蓝

为了观察光催化剂的反应，采用全回流水热法合成了rGO / ZnO / Cu纳米结构。评估了添加rGO和Cu掺杂对ZnO晶格的影响。FE-SEM，TEM，EDX分析和XRD测试用于研究催化剂的形态和粒径。XRD-SAXS验证了催化剂的结晶度。FTIR和拉曼光谱表征了矿物氧化物-GO键，并且DRS被用于研究带隙。用亚甲基蓝溶液研究了光催化降解效率，其中25 mg光催化剂是降解的最佳剂量。
